when it comes to bl that isn't smut centered, especially in mangas, since most of them are not long running series so it is less visible to readers. To get a feel if it's a good read, go through the comments section and weigh the opinion of the people.
Also, rating the story low for not having intense smut is just . I understand some readers like things with smutty scenes but to base your ratings largely on that? You need to re evaluate your criteria.
Anyway, this story is pretty wholesome and cute! Definitely worth reading if you want something light and fluffy after a stressful day.

Nah, let's not pretend that smut isn't one of the biggest drivers for gaining readers in BL. There have been lots of subpar stories that still obtain high ratings and readership because of the presence of sex scenes. Some people even confess sticking around despite the plot being all over the place just for the smut. On the other hand, good mangas like this are left to collect dust because they lack the plap plap plap factor.
Anyway, the second part of my comment is referencing that comment above.

Can someone tell me if it involves cheating, please? I've seen the first few pages and it seems like the mc is currently not with the love interest. I just want to know what to expect if I read this.

As of now theres no cheating (up to the current chapter), and from my gut feelings theres probably none in the story though im not 100% sure since i dont have the physical copy. Although from the way the story is going, i cant say who the mc will end up with (i sure do hope its not the married old friend tho)

Immediately trust supposedly authoritative figures, even teachers. Some of them get into this profession to prey on vulnerable individuals like children. Over the years, there were news of rapist and sa teachers who got reported by their students to the authorities. Many of them still got away scot-free AND were accepted by a different school when they quit. Both education and justice system is fucked up.
Getting revenge by vomiting on your bully is a first for me. Imagine that scummy guy walking in a crowded street and then riding the train or taxi; people avoiding him because of the stink. In a way, it represents his rotten personality lmao.
